thanx for your fast replay Sauraen. 3D-Printing...that didnt came into my mind the time i asked you about the switchcaps. Crazy new possibilitys with todays technologies! ;-) Regards MaG2k

wow...nice switchcaps...is it silicone? Where did you got them or how do you make them???? Best Regards MaG2k P.S.: very nice project!!!

Hi folks, here is a first test of my gear. SeqV4 is looping sequences of Depeche Mode's "Behind the Wheel" on three EMU samplers (one EMU E5000Ultra and two EMU ESI4000Turbo). Sorry for that terrible sound...i recorded it with my cellphone...it's my first run! Merry Xmas!!! MaG2k (i hope that it works with the embedded youtube-video, i have sometimes problems with it!)

Hi Thorsten, thanx for your fast help but i didn't checked you new software yet cause the problem was a much easier one. As you told the "*" means that the IIC module wasnt recognized by the core because of missing power. And so it was...one pin of the IIC-socket on the IIC-board was disconnected (could be the +5V Pin). I dont know why it came out but i reconnected him an now it is running fine again! thanx for your help! Best Regards MaG2k

Hey @ all, i have a little problem with my Seq V4 from one minute to the other it stopped sending notes to the IIC Midi Out. When i open the Midi-Monitor it shows me that the SeqV4 is allready sending notes to MIDI IIC OUT1 but nothing happend on the MIDI.machine that is connected to this MIDI OUT port. If i change it with an other MIDI port form the LPC17 Core the machine playing the notes. I rebooted the SeqV4 but still the same problem. What does it mean if i open the "Event-Menu" and select the IIC1 port when there is a " * " behind the "IIC1*"...does it mean the port isnt there? Or IIC is not working??? It happend from one minute to the other...i recorded a video a minut ago where all ports are running perfectly. Can anyone help me or give mie a hint? Best regards MaG2k

Thanx Altitude for your help! :-)

Thanx for your help. Yes i allready realised that the picture on the Mouser website doesn' match the parameters. Can you post / link your thread about improving contrast here? Thanx Regards MaG2k

Hey @ all, i am searching for a green negative display with 40x2 characters for my second SEQ V4. I found one at mouser that fit my parameters but i didn't found if the NT3881 controller of this optrex C-51850NFQJ-LG-ACN display is compatible to the HD44780 standard display driver. http://de.mouser.com/ProductDetail/Optrex/C-51850NFQJ-LG-ACN/?qs=%2fha2pyFadugV%252b8G4BKyno1j%252bOJ502VJJ3WoTXbvzA6fbvRZRg9MkNQ%3d%3d Does anyone of you used that display allready or isn't it working with this application (SEQ V4)? Thanx for your help! Regards MaG2k

thanx for that hint monokinetic, i looked arround in the settings of inkscape and saw that the prefered resolution for import/export is 90dpi...so i think inkscape is working with 90dpi. But i have a new problem. i started to edit around in the design form this thread in illustrator and tried to open the in illustrator saved svg-file in inkscape...but it doesnt work. i can't open the illustrator file in inkscape again. so i think i have to stay with illustrator :-) I think i use the next days to edit around a little and try to find out how inkscape an illustrator work! :-) Thanx again for you help! Regards MaG2k

hey Arkay, i found that Adobe opened it's old software for free download and use. so i installed Adobe Illustrator CS2 and opend the original design from here...everything is perfect...but then i tryed to open my svg-file that i allready modified in Inkscape till i realized that the measurements are wrong...and what happend...opend in Illustrator the measurements are also okay. its a little bit strange. I downloaded the master-layouts from formulor/ponoko for Inkscape and opend them in Inkscape...they have the correct measurement...only the Illustrator-Layouts opend in Inkscape are to small. But now i have found a way and think that i make it with Illustrator. i have to learn a little bit at first because i dont know how i can make exact measurement in Illustrator. i will try next time to create a layout in Autocad and export it as DXF and reimport it in Inkscape to make an svg-file...if that works with correct measurements it is better to design it in Autocad. i make the first steps with boxmaker and importing the pdf in inkscape or illustrator but does anyone has experiences with lasercutting-width? i ask because of the correction-factor that can be set on boxmaker to make the case fit better. what kind of value is good for that correctionfactor? Thanx a lot! Regards MaG2k

Back again...with new problems.. the design of smokestacksproductions is an Ilustrator svg-file. because i have only Inkscape i opend the file of smokestacksproductions and edited a bit around to "bend" the case to meet my demands as i realized that the P3 template (790x384mm) is to small in Inkscape. If you open the casedesign of smokestacksproductions in inkscape the outlines of P3 template is only 640x315mm in size so the rest of the casedesign is to small too...can anyone help me? I only have inscape and it would be nice not to design all from the begining. Regards MaG2k

Hi, can someone tell or discribe me how i get casedesign made on boxmaker (PDF) into an svg-file...i tryed to import the on boxmaker created casedesign in inkscape but i only got the text in the PDF-file end not the caselayout. how can i import it so that all the measurement are correct after import? Can anyone give me some hints? thanx a lot! Regards MaG2k i got it...:-) sorry for the question befor...the import was okay but i didnt saw the outline of the Case cause it had no color and no thickness! :-) MaG2k

Yes, its normal... The Main LED only flashes when something (datatraffic) is happen on one (, two, three, four or all) of each MidiPort (input also as output)...its only shows that there is traffic...its not like a power LED! Connect the MidiPorts...make something traffic on the MidiPorts an you will see that the MainLED is flashing in rythm of the Data of the traffic on the MidiPorts :-) regards MaG2k

hey Polykobol, were do you got the LRE8x1 from? Did you builded it for your self or with the help of Fairlightiii's PCBs...if the last one...as i remember correctly Fairligtiii isnt ready designing the LRE8x1 or did you mean you finished an LRE8x2? for the firmeware of the 32bit cores you have to use the MidiBox NG Firmeware http://www.ucapps.de/mios32_download.html and on the SD-Card you have to store the LRE8x2.ngc file http://svnmios.midibox.org/filedetails.php?repname=svn.mios32&path=/trunk/apps/controllers/midibox_ng_v1/cfg/templates/lre8x2.ngc from T.K. You have to change the file to fit your configuration. I didn't testet it with an 8bit core. because thatswhy i don't know much about the software and configuration on that...you should contact fairlightiii for that topic! Regards MaG2k

hi LRE8x2 builders, the problem i had with the glowing LEDs in the LEDrings is solved and documented here: regards MaG2k

Hi MIDIbox'ers, once again a video of me...showing the LRE8x2 now working correctly. The problem with the untriggered but glowing LEDs in the LED-rings is found and solved with the help of T.K. now. The problem was not a problem of defective LEDs or liftet grounds. It was a problem of the SN74HC595 and the UNLs (darlington transistor arry) it selfs. I first exchanged the 74HC595 with some which i bought from an other distributor and the result was that the glowing was extremly much darker after that and only localy. After i kicked out the ULNs and bridged them the problem was completely gone! So here is my warning: don't buy IC at "tayda electronics". The LEDs i used are also bought at "tayda electronics" but they are okay...not all are good but look at the price...they cost half of that what LEDs costs at mouser, reichelt, farnell,....so if you buy those LEDs at tayda please calculate that 1-5% can have a problem! Of my 256 soldered LEDs i found 4 with defective LED-housing (broken LED-housing). what i tink is that "tayda" sells the parts directly from the factory without qualitychecking them! Once again...be warned! Best regards MaG2k

Hi Martin, all the knobs have reached some minutes ago...everythings fine...all knobs are counted and have the correct amount! Once again...thanx thanx thanx...great job!!! Thanx a lot! Let assembling beginn! :-) Thanx Best Regards Matthias

thanx for your fast response Thorsten! because of the shadows on the LED-rings...i will check that this weekend again but in can't imagine that i soldered wrong...but what i can imagine is that the ULNs itself has a problem because i ordered them too at tayda electronics and as i said in the video the LEDs aren't all the same quality. What i can imagine is that they have a little fault. but i will try it without the ULNs again. about the device_ID...i will check it right now! :-) Thanx for your help! Regards MaG2k

as i told some post before here...i uploaded a video-documentation of the first run and problems of my LRE8x2. you can find it here: Regards MaG2k

Hi "MIDIboxer's"... to day i partly finnished my LRE8x2 PCB driven by an LPC17 Core with uploaded Bootloader v1.011 and the MIDIbox NG application (and configurationfile http://svnmios.midibox.org/filedetails.php?repname=svn.mios32&path=/trunk/apps/controllers/midibox_ng_v1/cfg/templates/lre8x2.ngc). I recorded two videos (german and english version) of the first run. What you can see is a documentation of brightness of four different typs of LEDs. I allready updated the LED-Blacklist on fairlightiii's wiki-page: http://www.midibox.org/dokuwiki/doku.php?id=mb-lre8x2cs_pcb#whishlist But now the videos (english version): (german version): As i red on tayda electronics datasheetpage for the red T1 LEDs they shall have 3000-4000mcd! I can't realy imagine that because they arn't that bright. If you use them standalone driven without PWM (only DC). What i can imagine is that they are around 300-500mcd. As you can see i have some little problems and hope that you have ideas to solve that problems. Can it be that the glowing of the non triggered LEDs comes because i didn't assembled all the LEDs in the LED-rings of encoders 2,4,6,8,9,10,11,12,13,14,15 and 16? I used the ULN2803 transistor-darlington-array! @ T.K. do you have an idea why one off my cores isnt answering via USB-MIDI-ports and as well not on the native MIDI-ports? what i did was that i red about changing the USB_name of the Core (after uploading the bootloader-firmware) and the device_ID to. I changed the name to "MIDIbox NG LRE8x2" and the device_ID to 126 (because i will use more LPC17 Cores at the same time). What happend is...the bootloader starts and on the display is written "bootloader is up and running"...in the system is now a USB-MIDI IN and OUT port named "MIDIbox NG LRE8x2" but if i try to connect with MIOS Studio i get no connection (the core doesn't accept any upolads and he isnt answering to commends at the command-line). The only life-signals i get from the core is (if i connect him via native MIDI IN/OUT) in MIOS studio (if i choose the native MIDI-ports of my soundcard) is that the bootloader is up and running and the bootloader-version...but i can't send any commands also not via the native MID-ports. What can i do to bring him back to life? what did i wrong? For the LRE8x2 project that you see in the videos i used an other fresh core were i didnt changed anything. An other problem i realised was that if i connect the board which is not answering anymore to the PC and then connecting the GM5x5x5 device i also builded than all ports (the USB-MIDI port of the LPC17 Core and the USB-MIDI ports of the GM5x5x5 device) has the name "MIDIbox NG LRE8x2" in MIOS studio. The LPC17 Core starts with "MIDIbox NG LRE8x2" than the GM5x5x5 device starts with "MIDIbox NG LRE8x2" too followed by "MIDIbox NG LRE8x2 2", "MIDIbox NG LRE8x2 3"...and so on. Does anybody of you do have input for me? Thanx a lot! Regards MaG2k (Matthias) P.S.: please excuse my "not the best" english in the video! how can i embedd the youtubevideos here?

okay thats correct...once you start the BO you will definitly havn't any time to change designs! :-) But it is nice to hear and notice that "i am in" (i would like to take all different types of your new designs)! We all should test more different LED typs cause my video later today will show four differnt typs (that i allready added to the blacklist) and only one is okay for the LRE8x2 on an MIDIbox NG Core.

is there a kind of timeline for an BO of the 8x1, 4x2 and 4x1 Jerome? Would be nice to hear that you do an BO again! :-) later today i post my experience about the LRE8x2! at the moment i upload two videos on youtube! Regards MaG2k
